A balloon filled with gaseous hydrogen exploding.. A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. [1] In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas, methane, propane, butane.
Unless it breaks the water surface while still a hot gas bubble, an underwater nuclear explosion leaves no trace at the surface but hot, radioactive water rising from below. This is always the case with explosions deeper than about 2,000 ft (610 m). [6] About one second after such an explosion, the hot gas bubble collapses because:
The main component of the beetle spray is 1,4-benzoquinone, an irritant to the eyes and the respiratory system of vertebrates. The flow of reactants into the reaction chamber and subsequent ejection occur in a series of about 70 pulses, at a rate of about 500 pulses per second. The whole sequence of events takes only a fraction of a second.
The faulty procedure used caused natural gas to build up in homes within a matter of minutes. Multiple explosions and fires were reported over a very short period of time in the towns of Lawrence, Andover, and North Andover beginning about 4:15 pm . [9] Through the evening emergency crews responded to between 40 and 80 fires.
Explosion of unserviceable ammunition and other military items The explosion of the Castle Bravo nuclear bomb. An explosion is a rapid expansion in volume of a given amount of matter associated with an extreme outward release of energy , usually with the generation of high temperatures and release of high-pressure gases .
The massive explosion at the Sandman Signature Hotel in downtown Fort Worth, suspected as a gas leak, may be part of a worsening trend across the US. Gas leak explosions are happening more often ...

The creation of sparks from metals is based on the pyrophoricity of small metal particles, and pyrophoric alloys are made for this purpose. [2] Practical applications include the sparking mechanisms in lighters and various toys, using ferrocerium; starting fires without matches, using a firesteel; the flintlock mechanism in firearms; and spark testing ferrous metals.
